CLOCK-FRAME.

Specification of Letters Patent.

Patented Nov. 29, 1921.

To all whom it may concern:

Be it known that I, PAUL LUX, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, haveinvented certain new and useful Improvements in Clock-Frames, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in clock frames and more particularly to means for securing the back frame to the pillars, the object being to provide a construction of clock frame which can be quickly assembled.

Another and further'object of the invention is to provide a novel form of pillar which is stamped out'of sheet metal having a pair of lugs at one end adapted to pass through spaced openings in the back frame and be spread by a spreading tool so as to securely fasten the back frame to the pillars.

A still further object of the invention is to provide a novel means for securing the main spring to the'pillar by providing the end of the main spring with an elliptical shaped opening instead of a loop and one of the pillars with a lug ofiset therefrom over which is adapted to be placed the end of the spring in such a manner that the tension of the main spring will hold it in place, whereby a broken main spring can be readily replaced in the clock without taking the clock apart, as it is simply necessary to unhook the broken portion from the pillar and from the main arbor and rewind a new spring on the main arbor with the clock winding key and hook the free end of the spring over the hook on the pillar.

A still further object of the invention is to provide a clock frame in which the structural strength is increased by locating the pillars at various angles for if the plane of the pillars were parallel with the frame of the clock, it would have a tendency to bend in the direction at right angles to the plane of the pillars. By placing the pillars at various angles a rigid frame is formed.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings,

Figure 1 is a plan view of a clock frame constructed in accordance with my invention;

Fig. 2 is an elevation of the same, partly in section;

Fig. 3 is a plan view of the back frame;

Fig. 4 is a perspective view ofthe pillar having the lug to receive the end of the main spring of the clock; and

Fig. 5 is a perspective View of a slightly modified form showing the shoulder headed rivet secured to the pillar over which the end of the main spring is adapted to be hooked.

In constructing a clock frame in accordance with my invention I employ a front frame 1 and a back frame 2, the front being provided with openings 8 through which the reduced portions at of fiat pillars 5 are adapted to extend and be riveted as shown at 6. These pillars are preferably stamped of sheet metal and are arranged at an angle to the edges of the clock as shown in order to increase the structural strength of the frame. The other ends of the pillars are provided with spaced lugs 7 which are adapted to pass through spaced openings 8 in the back frame 2 and s read as clearly shown with a wedge-shaped spreading tool so'as to securely fasten the back frame on the pillars.

One or more of the pillars in constructing a clock frame are provided with ofiset lugs 9 which are adapted to receive the ends of the springs-1O and 11. The free ends of these springs are provided with elliptical shaped openings 10' and 11 through which are adapted to pass the lugs 9 for fastening the free ends of the springs to the pillars in such a manner that when one of the springs becomes broken, the old one can be readily removed and a new one inserted.

When it is desired to insert a new main spring, one end of the spring is hooked over the main arbor and the spring is wound thereon with the winding key and when the clock is almost fully wound up, the end is forced over the lug of the pillar and by continuously winding the spring the proper tension will hold the spring in position at all times and while I have shown this construction in use for holding both of the springs in the clock frame, of course, I do not wish to limit myself to the use of any particular number of pillars constructed *strength of the frame, said pillars beingwith lugs to receive .the end of a clock spring in constructing the main frame of a clock, as my invention consists broadly in forming a fiat pillar for a clock' frame with alugover which the end of the spring of the clock is placed and secured by the tension of the spring in such a manner that an old spring can be readily removed and'a new one inserted without taking the frame apart.

In the modification shownin Fig.5 1

have secured a shoulder rivet 12 provided with a head in an opening formed in the pillar 13 over vwhich the end-of the spring is placed, as I' am aware that instead ofiform ingtthe lug integralwith the pillar it could be formed separate and the same result obtained and therefore'I do not wish to limit myself to "the forming of a fiat, pillar with an integral lug to hold the spring."

From the foregoing "description it will be seen that" I' have provided a clock frame formed of a. pair of frainesc connected together by flat pillars arranged at various. angles so; as to increase the structural secured to the, frontjframein a novel manneii in order to allow the back' frame to be readily attached, one or more of the pillars being provided with a lug to receiveand hold the end of the spring in sucha manner that the spring, can be readily inserted or removed. t

I have found in, practice that preferably sheet metal is used for forming the pillars but it is; of course understood that any other suitable material can b e used and therefore I: do not wish tolimit myself to the-use of anypa'rticular'kind of material in form, ing the pillars. i

I have described the pillars being fixed to the front frame and detachably secured to thefback fram'e of the clock, but it is, of.

course, understoodthat in constructing some kinds of clockframes. the I pillars could .be

secured tothe back frame and detachably secured to'thefront frame'and in fact, I do tolimit myself'to these details of construction as my invention consists broadly in constructing. a clock frame with flat pillars det'achabljf'coMectedft one of the frame Inembers'having lug or hook adapted to pass through an opening formed in the end of'the spring for holding the spring within 7 the clock" frame in such a ma merthat it can be readilydetached for removing a broken spring and inserting a new spring.

What I claim is 2- frame having spacedlugs at. their ends;

the back; frame. being'provi'ded with spaced openings to receivesaid lugs, said lugs being adapted to be pread apart "for fastening theback frame thereto. i
